管道内瓦斯爆炸压力的传播研究

Study on the Spread of Gas Explosion Pressure in Pipeline

对瓦斯气体在管道内的爆炸过程进行了初步研究。根据实验结果将压力传播的变化过程分为前驱冲击波、升压、降压、余波4个阶段,并对各阶段中的压力传播状况进行了分析。结果显示,瓦斯气体在管道传播过程中,出现冲击波反射、波叠加及二次反冲现象,为管道内及煤矿巷道爆炸的预防提供了参考。

This paper conducts studies on the explosion process of methane gas in the pipeline. Based on the experimental results, the spread of pressure can be divided into four stages, precursor shock wave, boost, buck and remainder. The results show that the gas in the pipeline spreading process presents the shock wave reflection, the superpesition and two recoil phenomenon, which provides references for the pipeline and coal tunnel explosion prevention.
